Abstract

Composite body made of thin-walled elements (2) in the manner of cooling ribs and a supporting body (3) which is not substantially thicker and into which the thin-walled elements are inserted. According to the invention it is provided that the thin-walled elements (2) are interrupted in the manner of groove (4) and tongue (5) and are connected to the supporting body (3) as a result of the fact that the supporting body (3) is produced by casting. <IMAGE>

Description

Verbundkörper aus dünnwandigen ElementenComposite body made of thin-walled elements

und einem Tragkörper Die Erfindung bezieht sich auf einen Verbundkörper aus dünnwandigen Elementen nach Art von Kühlrippen und einem nicht wesentlich dickeren Tragkörper, in den die dünnwandigen Elemente eingefügt sind.and a support body. The invention relates to a composite body of thin-walled elements in the manner of cooling fins and one that is not significantly thicker Support body into which the thin-walled elements are inserted.

Bei dünnwandigen Elementen, die federartig in eine Nut eines Tragkörpers eingefügt sind, besteht bei einem Tragkörper, der nicht wesentlich dicker als die dünnwandigen Elemente ist, die Gefahr, daß der Tragkörper durch die dünnwandigen Elemente so geschwächt ist, daß er brechen kann. Aus den verschiedenartigen Gründen kann es jedoch erwünscht sein, verhältnismäßig dünne Tragkörper zu verwenden. Das ist beispielsweise bei Aggregaten zum Kühlen oder Heizen mit Peltier-Elementen der Fall, wo zahlreiche Kühlrippen in verhältnismäßig dünnen Tragkörpern stabil zu halten sind. Dünne Tragkörper sparen nicht nur Material, sondern sie sind auch aus konstruktiven Gründen wünschenswert.In the case of thin-walled elements that are spring-like in a groove of a support body are inserted, there is a support body that is not significantly thicker than the thin-walled elements is the risk that the support body through the thin-walled Element is so weakened that it can break. For various reasons however, it may be desirable to use relatively thin support bodies. That is for example in units for cooling or heating with Peltier elements Case where numerous cooling fins are kept stable in relatively thin support bodies are. Thin support bodies not only save material, they are also made from structural engineering Reasons desirable.

Der Erfindung liegt die Aufgabe zugrunde, einen Verbundkörper zu entwickeln, der dünnwandige Elemente in einem nicht wesentlich dickeren Tragkörper sicher hält.The invention is based on the object of developing a composite body, which holds thin-walled elements securely in a not significantly thicker support body.

Die Lösung der geschilderten Aufgabe besteht nach der Erfindung darin, daß die dünnwandigen Elemente nach Art von Nut und Feder durchbrochen sind und mit dem Tragkörper dadurch verbunden sind, daß der Tragkörper in Gußtechnik hergestellt ist. Insbesondere kann der Tragkörper bei einer Gießrichtung im wesentlichen senkrecht zur Ebene der dünnwandigen Elemente gegossen sein.The solution to the problem described is, according to the invention, that the thin-walled elements are perforated in the manner of tongue and groove and with the support body are connected in that the support body in casting technology manufactured is. In particular, the support body can be essentially perpendicular in one direction of casting be poured to the plane of the thin-walled elements.

Tragkörper und dünnwandige Elemente können beispielsweise aus Aluminiumlegierungen ausgebildet sein, wobei die dünnwandigen Elemente Bleche sein können.Carrier bodies and thin-walled elements can, for example, be made of aluminum alloys be formed, wherein the thin-walled elements can be sheets.

Durch das Ausgießen der nutartigen Stellen an den Blechen durch das Material des Tragkörpers wird der Tragkörper durch durchgehende trägerartige Gußstränge ohne Gefügestörung verstärkt. Dabei können diese Gußstränge eingebettet sein, in der Materialdicke des Tragkörpers. Wesentlich ist dabei weiter, daß beim Schrumpfen des Gußmaterials die dünnwandigen Elemente an ihren schwalbenschwanzförmigen nutartigen hinterschnittenen Ausnehmungen zur Basisebene herunter- bzw. festgezogen werden. Dadurch wird nicht nur Wackeln vermieden, sondern auch der Wärmeübergang sichergestellt.By pouring out the groove-like spots on the metal sheets through the The material of the support body is the support body through continuous support-like cast strands Reinforced without structural disturbance. These cast strands can be embedded in the material thickness of the support body. It is also essential that when shrinking of the casting material, the thin-walled elements at their dovetail-shaped groove-like undercut recesses are pulled down or tightened to the base plane. This not only prevents wobbling, but also ensures heat transfer.

Die Erfindung soll nun anhand eines in der Zeichnung grob schematisch wiedergegebenen Ausführungsbeispiels näher erläutert werden: Der Verbundkörper 1 besteht aus dünnwandigen Elementen 2 und einem nicht wesentlich dickeren Tragkörper 3. Die dünnwandigen Elemente 2 sind parallel zur Zeichenebene angereiht und mit dem Tragkörper 3 nach Art von Nut und Feder verbunden. Hierbei sind die dünnwandigen Elemente unabhängig von der Art der speziellen Ausführung an Stellen verjüngten Querschnitts, also in ihrem Nutbereich 4 bzw. im Federbereich des Tragkörpers, vom Tragkörper umschlossen. Die dünnwandigen Elemente 2 sind nun mit dem Tragkörper 3 dadurch verbunden, daß der Tragkörper bei einer Gießrichtung senkrecht zu den dünnwandigen Elementen 2 in Gußtechnik hergestellt ist. Die dünnwandigen Elemente 2 können zunächst ihrerseits in Gußtechnik oder als Bleche hergestellt worden sein. Hierauf werden die dünnwandigen Elemente 2 in den Guß des Tragkörpers einbezogen, wobei sie mit ihrer Nut 4 durch die vom Guß gebildete Federn 5 ausgefüllt werden.The invention is now based on a roughly schematic in the drawing illustrated embodiment are explained in more detail: The composite body 1 consists of thin-walled elements 2 and a not much thicker support body 3. The thin-walled elements 2 are lined up parallel to the plane of the drawing and with connected to the support body 3 in the manner of tongue and groove. Here are the thin-walled Elements tapered in places regardless of the type of special design Cross-section, ie in its groove area 4 or in the tongue area of the support body, from Enclosed support body. The thin-walled elements 2 are now with the support body 3 connected in that the support body in a casting direction perpendicular to the thin-walled elements 2 is made by casting. The thin-walled elements 2 may initially have been manufactured using casting technology or as sheet metal. Then the thin-walled elements 2 are included in the casting of the support body, where they are filled with their groove 4 by the springs 5 formed by the casting.

Durch Strukturuntersuchungen, beispielsweise durch Schliffbilder, läßt sich feststellen, ob die Gießrichtung in der beschriebenen Weise ausgerichtet ist.Through structural examinations, for example through micrographs, it can be determined whether the pouring direction is aligned in the manner described is.

Wenn die Gießrichtung auch für beste Ergebnisse förderlich ist, so vermindert man schon durch die übrige Ausbildung der dünnwandigen Elemente 2 und des Tragkörpers 3 die Bruchgefahr des Tragkörpers und verbessert auch den Wärmeübergang.If the pouring direction is also conducive to the best results, then so is already reduced by the rest of the formation of the thin-walled elements 2 and of the support body 3, the risk of breakage of the support body and also improves the heat transfer.
